Prior to working with the trigonometry formulas/laws of cosines, learners should understand Pythagorean's Theorem, area and perimeters of triangles as well as having a strong understanding of angles. Typically, sin and cosine are addressed in the ninth or tenth grades in most jurisdictions. Functions consisting of products of the sine and cosine can be integrated by using substitution and trigonometric identities. These can sometimes be tedious, but the technique is straightforward.
